  • All Implemented Interfaces:
    Direct Known Subclasses:
    InputEvent, OutputEvent, WindowEvent

    public class NEWTEvent
    extends EventObject
    NEWT events are provided for notification purposes ONLY;

    • MouseEvent 200..20x
    • KeyEvent 300..30x

        public final void setConsumed​(boolean consumed)
        If consumed is true, this event is marked as consumed, ie. the event will not be propagated any further to potential other event listener. Otherwise the event will be propagated to other event listener, the default.

        The event is marked as being consumed while attaching the consumedTag.

        Events with platform specific actions will be supressed if marked as consumed. Examples are:

      • toHexString

        public static String toHexString​(short hex)
